I do this all the time using SFTP
Because I use Linux I just drag and drop using the Konqueror file manager, but you should be able to find a reasonable GUI SFTP client on any platform.
There is no real reason to use FTP any more. Sending passwords in plain text is not good security, and FTP does nothing to verify that you are connected to the server you wanted to be connected to either.
